I dont play that often anymore but i have never done my seals and i know if i took my gun it would work. I only took it apart one time to oil it. Trust me i have given the gun a beating and it still works great. So for what you looking for the tippman would be a great gun. Only mod i did to it was a bigger barrel its all i ever needed. I know its not the best gun but for the money its worth the reliability
